The GRACO 184053 SEAL, PISTON (4.5 CM) is a piston seal designed for use in GRACO pumps. It is typically made from UHMWPE (Ultra-High Molecular Weight Polyethylene), a material known for its durability and resistance to wear. This seal is intended to ensure a tight fit and prevent leakage between the piston and its seat within GRACO pump assemblies.

Key Features:

• Piston Seal
• 4.5 cm
• UHMWPE (Ultra-High Molecular Weight Polyethylene)
• Compatible with GRACO Check-Mate 450 and similar pump models
• High wear resistance
• Reliable sealing performance
• Designed for easy replacement during maintenance

Applications:
Used in GRACO pump assemblies to maintain seal integrity and prevent fluid leakage during operation. Suitable for industrial, mining, and agricultural lubrication and maintenance applications.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment.
• Always install a new piston seal during pump maintenance or rebuild
• Apply thread sealant as recommended in the manual
• Ensure proper torque is applied to related components (e.g., piston seat: 27–34 N.m or 20–25 ft-lb, as specified in the manual)
• Follow all safety and maintenance guidelines provided by GRACO
